Dtdw- down to do whatever. Usually involves smoking weed and roaming around, hitting up cheap restaurants and 2 dollar movie theatres or just doing something by a beach or river area.

standard

can be used to describe a girl or (less often) guy who is not DTF but pretends to be in order to receive free wine or other alcoholic beverages from the other person. The reason why it is wine instead of beer or spirits is that wine-drinking girls are statistically more posh and less likely DTF.

Guy1: Dude u seen dat girl over there? she's been hangin' out with that guy all evening, think she's DTF?
